MACHINE FOR SHAPING UPPERS.

Specification of Letters Patent.

Patented Sept. 5, 1916.

Application led October 28, 1912. Serial No. 728,183.

To all whom z' may concern Be it known that l, MATTHIAS BROCK, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Machines for Shaping Uppers, of which the following description, in connection with the accompanying .drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

rlhis invention relates to machines for shaping the heel portions of shoes and is herein embodied in a machine for preliminarily molding the upper materials, including the heel stifener, of a shoe prior to assembling said upper materials with the innersole upon the last over which the shoe is to be made. y

By molding the shoe upper with its lining and the heel stiffener all together and under 'heavy pressure the unity of the upper materials is made more complete with the result that they supplement one another and also that a trimmer and less bulky appearance in the shoe is obtained. By molding the upper materials preliminary to assembling the shoe the use of metallic formers is made possible with the aid' of which greater and more effective molding pressure can be applied than wooden lasts would endure and the work can be most effectively treated with heat for rendering its shape permanent. Furthermore the shaping operation can thus be carried farther and made more effectual by using foi-mers that overmold the work to an extent to compensate for its inevitable reaction after it is freed from the shoemaking apparatus. Preferably the shaping operation on the upper materials is carried far enough so that, after making allowance for the reaction, the heel portion ofl said materials will acquire permanently the shape which they should have in the completed shoe after its last has been withdrawn. vOne furtheradvantage that is most useful in boot making is that the formers may comprise means, such for example as herein shown, for shaping the ankle and leg portion of the upper materials which extend above the top face of the usual last and are not ordinarily treated in lasting operations.

y It will be understood, however, that many if a shoe last is employed as the inside former. The machine is shown as a multiple unit apparatus in which three shoes remain under pressure to render the shape permanentwhile one shoe is being applied, and the units are so connected that the shoe which has been longest in the machine is automatically ejected simultaneously with the insertion of a fresh shoe to economize time and'effort of the operator; v

An important feature of the invention consists in improved means for holding the inside former. As herein shown the former is connected with novel mechanism for drawing the work into the machine and for compressing the work.

Another feature of the invention consists in novel means for obtaining a molded shoe upper which shall snugly fit the last when the shoe is assembled. In the illustrated embodiment of this invention the materials of the rear part of a shoe upper, including the heel stiifener, are molded overv an inside former which is narrower than the corresponding portion of the last for which the upper is being prepared and the former has its curvatures exaggerated. Preferably the mechanism is constructed and arranged to maintain the work under pressure and heat to set. v

Another feature of the invention relates to. the controlling mechanism for the machine. As shown the machine comprises four molding mechanisms for each of which an operating mechanism is provided, and a treadle for each mechanism has also a novel connection with another mechanism` by which one mechanism is made to carry work into position of pressure and another mechanism is made to eject the work which has been under pressure.

Another important feature of the invention consists in improved -outside formers.

In the drawings these are shown as including backing plates to which face plates are movably connectedv for adaptation to conditions presented by the work and also for vertical movement with the inside former;

4A further feature of the invention consists in novel work positioning devices to Further features of the invention consist in novel means for tensioning the upper about an inside heel former preparatory to molding; novel means to produce a snug fit of upper materials over the ball of the heel of the wearers foot; novel means for driving tacks from inside a shoe upper outwardly and novel means for shaping the leg portion of boot uppers.

These and other features of the invention, including certain details ofl construction and combinations of parts, will now be more fully described in connection with the accompanying drawings and will then be pointed out in the claims, except the novel method herein disclosed which is claimed in co-pending application Ser. No. 62,041, liled Nov. 17, 1915. In the drawings, Figure 1 is a right hand side elevation lof the machine; Fig. 2 is a plan View; Fig. 3 is a front perspective of the lower portion of the machine; Fig. 4 is a perspective view showing the inside former and the neck and leg crimping devices in open position; Fig. 5 is aside elevation partly in section showing the shoe carrier and inside former drawn into the machine; Fig. 6 is a plan view in sectionV being located between the heel seat formers and the outside molds; Fig. 6 is a plan view of the heel seat forming plates and their operating mechanism; Fig. 7 is a perspective view illustrating particularly the inside former with its gages and flange Shapers and the gripper mechanism; Figs. 8 and 9 are views showing in full and dotted lines the principal cam tracks.

The machine is shown as a quadruple apparatus comprising four like molding mechanisms coupled up sothat one is caused to free a shoe when a shoe is put under forming pressure in another and while two shoes stand under pressure in the third and fourth mechanisms. The fourth mechanism at the right hand side of the machine has been selected for illustration and duplication of reference characters on the drawings will be omitted in the interest of clearness.

The main shaft 2 is driven from a pulley 3 and turns in bearings formed in the end nwalls 4 and similar `partition walls that are located between each pair of' 'the mechanisms, said walls being tied together by rods 6, 7, 8, 9, 10 and 11 which serve as fulcra for variouslevers, etc., which will be mentioned.` These walls with the floor base constitute the machine frame and upon the walls is mounted a head plate 12 which is recessed in its front face to receive and support the outside molds and the wipers and which is covered by a cap plate 14.

"Motion is transmitted from the main shaft l -2 to the cam shaft 5 through speed reducing gears 15, 16 the gear 15 being connected to the'main shaft by a Horton clutch thek stop pawl 18 for which is withdrawn to start the gear 15 and the mechanism operated by that gear by a connection 20, 21., 22, 23, Figs. 1

and 3 to a sleeve24 which is loose onthe rod 11, being moved in the direction to withdraw the clutch pawl 18 by a starting treadle. There are four starting treadles each of which is arranged to trip the clutches of two of the four molding mechanisms, the connections to said mechanisms-being so arranged that one mechanism carries the shoe just prepared into molding position and the mechanism in which ,a shoe has been longest under pressure forces that shoe out into position to be removed from its carrier. The starting treadle which causes the, right hand mechanism to carry a shoe into the machine is the treadle located at the left hand end of the machine and which at the same time causes the left hand mechanism to force out the shoe that has been under pressure in that mechanism. This result is obtained by pinning the hub of the left hand treadle to the treadle rod 11 and providing said rod, near its right hand end, with a fixed collar having a shoulder which abuts against a shoulder on t-he sleeve 24 above mentioned. From this arrangement, which is clearly shown in Fig. 3 of the drawings, it is plain that the treadlelever 25 at the left hand end of the machine can be made to start the mechanism at the right hand end of the machine. It may also be seen from Fig. 3 that the hub of each start-` ing treadle has a shoulder 26 which, when the treadle is depressed, will engage a shoulder 27 on the adjacent sleeve `24 and turn that sleeve. This movement of that sleeve for the left hand molding mechanismv starts that mechanism and causes it to eject the shoe which it has been holding under pressure. Each of the Astart-ing treadles except the left hand one carries on its hub a laterally projecting rod adapted to engage a lug standing up from the sleeve 24 which is at the left hand side of the hub and to cause the molding mechanism that is connected with that sleeve to draw into molding position a prepared shoe at the same time that a molded shoe is being forced out of the next mechanism at the right of the one into which the shoe yhas been drawn; springs 28 maintain the treadles normally elevated. After the. clutch has been closed and the machine started the pawl is held away from the clutch by a rod 30, Fig. 1, the upper end of which is connected to an Return arm 32 that is hung on rod 8 and has a roll ,l

engaged by the peripheral face of a cam -disk 85 formed integral with one side face of pressure respectively. There is a brake disk 36 fast with the gear 15 and a brake strap 38 encircles this disk and is connected with the clutch pawl operating mechanism to be applied when the pawl is set to open the clutch and to be released when the pawl is withdrawn for starting the gear 15.

A work support or jack post 40 has its foot mounted to slide in and out horizontally in guides Jformed on the walls 4, Flgs. 1 and 3, such movement being transmitted thereto through a connectin rod 42 and lever 44. swung from rod 6, Fig. 1, and carrying a roll that stands in a cam path 45 in the side of cam disk 35, Fig. 8. This cam path is formed to project the jack post alternately to shoe receiving position and draw it into the shoe shaping mechanism.

lVithin the jack post 40 a plunger 46 reciprocates vertically and carries the inside former. This movement is transmitted to it by a toggle 47, 48, a toggle operating link 52 and a lever 54 fulcrumed on rod 8, Fig. l, and carrying a roll that stands in a cam path 50 in a disk 55, Fig. 9, that is fast on the cam shaft 5, being back of pinion 16 in Fig. l. The plunger 46 is formed in two sections.l Figs. 1 and 5, between which is interposed a spring 58 to provide for yielding vertical pressure on the work and for a final movement of the lower section of the plunger relatively to the upper section 56 thereof for another purpose which will later appear. The plunger is directly over the thrust pin 57. of the toggle in position to be operated thereby when the ack presents the shoe within the shaping devices, and when the jack is advanced as in Fig. 1 to shoe receiving and delivering position the plunger is restrained from falling by a pin 59 which extends from the jack post therethrough in l a slot.

On the head of plunger section 56 is the inside former 60 the general shape of which corresponds to the rear part of a last from about the middle of the shank to the heel end, the former, however, preferably vary-r ing from the contour of the last in that it is vnarrower and its curvatures are exaggerated which have in their faces that are adj acenty to the jaws, see Figs. 5 and 6, grooves or recesses to receive tongues or ribs projecting from the jaws and by which the jaws are sustained for movement towardl' and from the backing plates. This movement is limited by pins 7 3 extending through the ,tongues on. the jaws and through enlarged ,formers can rise with the shoel when the inside former 60 is elevated, thereby avoiding downward drag on the shoe stock with which the jaws are in engagement. The backing plates 72 have arc-shaped guide ribs, see dotted lines Fig. 6, .standing in a circular groove in the head 12 and are operated to close upon a shoe applied tothe inside former by means of the links 78 connecting them with the crosshead 79 of the thrust pin 8O of a toggle 81, 82, Fig. 1, which is operated by a link connection 84 with a roll standing in a cam path 85 formed in that side of the cam disk 55 which is opposite to the path 50. The toggle has an adjustable abutment n83 through which the spread of jaws can be varied.

The seat wipers comprise preferably the construction of lasting plates shown in Figs. 6" and 7, and which are fully described and claimed in my earlier application for Letters Patent of the United States Serial No.

7 06,655, said plates being herein designated 100 generally by the reference character 90. They are operated to wipe the flange of the upper materials inwardly upon the top face of the inside former 60 by movements of the wiper parts each in a direction substantially 105 movement. Movement is transmitted to the 11u wipers through their carriers 91, which have pin and slot guiding connections with cap plate 14. The carriers are connected by links 92 to the crosshead of a plunger 93,

which is connected by links 94 toa rock 115 shaft 96 which is moved by a link 98"from a cam path 95,Fig. 8, in the side 'of the gear 16 which is opposite to that in which the jack post sliding cam path 45 is cut.

The neck crimping jaws 100 are arranged 12o vertically to engage the work in the region of the neck of a boot, which is at and below the top of an Oxford shoe and just at or about the upper edge of the heel stiffener in a bal .shoe or a. high boot, and crimp the 125 upper materials, including the stiffener, 1nwardly to produce a snug fit over the ball of the heel of the wearer of the shoe. This engagement is timedto occur after the outside ormers close.

Associated with 'the 130 crimping jaws 100 for boot work isa iiexible strip of leather or thin sheet metal secured to carrier blocks which are pivotally connected together in the middle, as best shown in Fig. 5, by a vertical pin 105 against which acts a spring pressed plunger 105. The free ends of the carrier blocks, see Fig. 4, are connected by links 104 to the plunger 103 in which the spring pressed plunger 105 is guided as shown in Fig. 5. The pressure of the plunger 105 forces the connected ends of the carrier blocks, and therefore the middle portion of the leg band, normally forward and maintains the leg band normally open to be engaged and closed and thrust backward by the shoe as the jack post is drawn into the machine whereby initial clamping of the leg of the shoe is effected. The plunger 103 is embraced by a thimble sleeve 106 which contains a. spring 108 and is traversed by a rod 109 fastened into the plunger and extending through a slide block 110 that is actuated by a link 112 and a v bell crank 114 connecting with al cam formed on the periphery of disk 55. This cam gives the final closing pressure to the leg band and thereafter, and after the outside fdrmers have been closed, through a lost motion connection 111 between the block 110 and the plunger 101, said cam advances and closes the neck crimping jaws 100, which are connected to their plunger by links 115 to stretch the stock between the band and the formers for producing the ci'imp.

Tack drivers 120 are mounted in the in- Side former as shown in Figs. 4 and 5 to insert tacks from the inside up through the overwiped margin of the upper, and it may be into a connecter for holding the two sides of the upper from spreading after the work is removed from the machine. These drivers are advantageously located near the outer edge of the inside former which is comparativel narrow at its lower face, thus rendering di cult the use of ordinary driver bars. I have therefore formed the driver passages in the former crooked as in Fig.

5 and interposed, as a movement transmitter between the drivers 120 and short bars `122, a series of balls 125 through which the tack driving force is transmitted. The bars restl upon a driver plate 126 which is supported by., rods 128 that extend through the head of the jack postl40 and into a collar 130 which is adjustable upon the lower jack plunger section 46 whereby the drivers are operatedl when the spring 58 yields.

The grippers, Figs. 1, 2, 5 and 7, for stretching the upper forwardly and drawing it snugly around the rear end of the inside former before the outside formers close,

are mounted on a carrier 135 that is connected loosely to an extension of the rock shaft 96 and the vertical position of which s determined by astop screw 136. A carrier rod 138 projects forwardly being encircled by spring 140 and sleeve 142 upon which the gripper block 144 is shiftable for the length of the shoe. The block has a. depending arm on which the upper jaw 145 is fixed in a position toengage the middle of the toe of the upper. The lower jaw 146 is pivotally mounted and has a rear arm to which closing movement is imparted yieldingly through spring 148 and connections comprising rod 150, rocker 152 which is splined on shaft 154 and has a rigid arm 155 joined by link 156 to a" connection with a cam 160 on one lateral portion of the periphery of cam disk 55 which closes the jaws when the machine is first started and holds them closed while the shoe is in the machine. The rocker 152 has a second arm 162 connected by a link 164 with a swinging pawl 165 which it lifts into engagement with ratchet teeth on the lower side of sleeve 142 when the gripper jaws are closed. While the jaws are open the operator can freely slide the gripper .block longitudinally of rod 138 and shaft 154 to position the jaws with the toe of the upper between them. When the machine is started the jaws close and the shoe is drawn by the jack post into the machine and away. from the jaws, which can, however, yield by reason of spring 138. In place of the automatic lock 162, 164, 165 a manual latch 170 may bel used.

The inside former is chambered to receive an electrical heating cartridge 175 and the outside formers are heated by electrical units 176 from which heat is also communicated to the wipers 90. Separate controls, not shown, are provided by which either or both the formers can be heated. The inside former may have on its top face, for shaping uppers for welt shoes, shoulders or ribs 180 located at a distance from the edge of the form corresponding substantially to the width of the feather of the innersole with which the upper is to be assembled and extending back as far as the heel breast line, the outer edges of the shoulders or ribs being preferably undercut. With these ribs or shoulders will be used wipers the edges of which have a coperating formation as at 182, Fig. 7, to mold the marginal portion offthe upper materials, inoluding the heel stiifener, into an upstanding lip to fit against the rib of the innersole to which said materials are to be attached. The rear end of the lip so formed'constitutes a gage mark formed in the upper to indicate the proper points of division between the heel seat tacking and the inseam sewing operations. The ribs or shoulders 180, by projecting above the inside former, constitute a height gage to guide the operator in placing the upper upon the inside former so that the right amount of material will be available for forming the heel seat flange. Alternatively movable height gages 185 l(Fig. 6) may be used which stand normally at or near the outer edge of the top 'face of the former, and therefore more closely adj acent' to the upper materials than do the ribs 180, and can moveinwardly with the .Wipers to avoid interference with the wiping operation.

In the use of the machine the upper is applied to the inside former when the jack post is in its forward position.. The gripper is adjusted longitudinally on its carrier to a position appropriate for the length of the shoe and the toe of the vamp is positioned in it while the heel of the upper is positioned vertically with the. assistance of the height gages to afford the stock necessary' to form the desired width of heel seat flange." The treadle 25 is then depressed to start the power mechanism which produces the several automatic operations in the following order: The grippers are first closed and are locked on their carrier. The jack post carries the inside former backward thereby stretching the upper and drawing it snugly about said former which proceeds into the outside formers, the gripper spring 140 yielding when its tension has been exceeded. The outside formers now close and the heel seat wipers close partially for initially breaking down the flange of the upper and heel stiifener after which they back olf and the inside former is raisedabout one eighth of an inch to bring the heel seat nearer to the alane of the wipers. The leg band, which was in position to be engaged by the leg of the boot when the jack moved back at the starting lof the machine, is now closed firmly and then the crimping jaws are closed and stretch, in the direction of the height of the shoe, the upper which is between the outside formers and the leg band and crimp it inwardly to fit around the wearers foot just above the ball of the heel.

This being in progress the wipers fully close over the heel seat, forming the upstanding flange' just forward of the heel breast' line if the shoulders or ribs 18() are used, and then the plunger sections are actuated to elevate fully the inside former for compressing the heel seat materials between the inside former andthe wipers. this elevation the tack drivers are. operated to insert tacks upwardly from the inside of the shoe through the heel seat materials that are held by the wipers. A connectingk strip may have been applied upon the top face of the inside former in position to be thus fastened by the tacks to the'upper mater1als at opposite sides of the heel seat to prevent4 spreading after the upper is removed from Duringor both ofthe formers, the three or' more brace or reinforce the others. The depres-v sion of treadle 25 will have closed the clutch not only 'for the right hand apparatus which has been particularly described, but also, by turning the treadle rod, for the left hand orNo. l apparatus in which, it will be assumed, a shoe has been longest under presr sure 'and on this treadling the cams ofthe No. l` apparatus will have been run through that portion of their cycle in which the shoe is released` and the jack post advanced to position for the molded work 'to be removed and a new'upper to be applied. The formation of the cams is such that the former 60 is lowered before the wipers are backed off the heel seat so that dragging of the wipersv outwardly over the heel seat is avoided. F

This application is a continuation of my co-pending application Ser. No. 637,655 as to certain subject-matter that iscommon to both applications. 4The novel method herein disclosed is claimed in my application Ser. N0. 62,041,5led NOV. 17, 1915.
